Abstract:

Using VLBA polarimetry, we derived distributions of Faraday Rotation Measure (RM) and projected magnetic field of 3C 273 jet. Based on a systematic gradient across the jet of RM and the projected magnetic field, the helical magnetic field is revealed, which is suggested by MHD s. The sign of RM indicates the direction of the twist of the helical magnetic field as a right hand screw. If the observed helical magnetic field is wound up by the accretion disk around possible super-massive black hole, we can see the direction of the rotation.
